At the middle of the mercury barometer tube there is a little column of air with the length `l_(0)` and there is vacuum at the top as shown. Under the normal atmospheric pressure and the temperature of `200K` `l_(0)=10cm`. What will be the length of the air column if the temperature rises to `330` kelvin? (Neglict expansion of the tube)

A barometer tube is inclined at an angle of 30^@ with horizontal direction. Calculate length of mercury column in tube if atmospheric pressure is 76 cm of mercury.

An ideal gas is trapped between a mercury column and the closed-end of a narrow vertical tube of uniform base containing the cloumn. The upper end of the tube is open to the atmosphere. the atmosphric pressure equals 76cm of mercury. The lenghts of the mercury column respectively. What will be the length of the air column when the tube is tilted slowly in a vertical plane through an angle of 60^(@) ? Assume the temperature to remain constant.

In the given figure, atmospheric pressure p_0 = 1 atm and mercury column length is 9 cm. Pressure p of the gas enclosed in the tube is

A satellite revolves round the earth. Air pressure inside the satellite is maintained at 76 cm of mercury. What will be the height of mercury column in a barometer tube 1m long placed inn the satellite?

Calculate the length of mercury column in a barometer tube which is inclined at an angle of 45^(@) with horizontal direction if the atmospheric pressure is 75 cm of mercury.

One metre long tube, closed at both ends, is lying horizontally. A mercurry column of length 0.1 m is filled in its middle and in rest two parts air is filled at atmospheric pressure. What will be the displancement of the mercurry column when the tube is turned to vertical position ? Atmospheric pressure = 0.76 m of Hg.

A faulty barometer contains certains amount of air and saturated water vapour . It reads 74.0cm when the atmospheric pressure is 76.0cm of mercury and reads 72.10cm when the atmospheric pressure at the air temperature=1.0cm of mercury. Find the length of the baromerer tube above the mercury level in the reservoir.

In a resonace tube experiment the lengths of the air columns for the first and second resonace differ by 25 cm . What is the wavelength of the sound in the tube ?
